Synthesis and Structural Characterization of Di(2-amino-5-methyl-1,8-naphthyridin-1- ium-7-carboxylato)dichlorocuprate(Ⅱ) Dihydrate

摘要

Di(2-amino-5-methyl-1,8-naphthyridin-1-ium-7-carboxylato)dichlorocuprate(Ⅱ) ditrated hydrochloride acid, and its structure was determined by X-ray diffraction at 298 K. The compound (C20H22Cl2CuN6O6, Mr = 576.88) crystallizes in monoclinic, space group P21 with a =9.102(9), b = 12.150(12), c = 10.619(10) (A), β = 91.20°, V = 1174.1 (19) (A)3, Z = 2, Dc = 1.632 g/em3,F(000) = 590, μ = 1.208 mm- 1, R = 0.0392 and wR = 0.0984. The Cu2+ ion is six-coordinated by two nitrogen and two oxygen atoms from two different naphthyridine ligands at the equatorial positions together with two chloride ions located at the axial positions.
